The Black Bay Fifty-Eight “Navy Blue” gets its name from its colour, of course, but also from the year 1958, in which the first Tudor divers’ watch waterproof to 200 metres (660 ft), reference 7924 or “Big Crown”, was presented. Among other aesthetic nods to this historic watch, this model offers a 39 mm diameter case in in keeping with the characteristic proportions of the 1950s. Ideal for slim wrists, people who like more compact watches and vintage enthusiasts, the Black Bay Fifty-Eight “Navy Blue” also carries on with the long Tudor tradition of blue sports watches.
